Where should the XLibre modules go?

XLibre creates a sub-directory with its ABI version under the ${PREFIX}/lib/xorg/modules/ .
The tree looks something like this:

${PREFIX}/lib/xorg/
|--modules/
|   |--drivers/
|   |   `--driver.so
|   |--extensions/
|   |   `--extension.so
|   |--input/
|   |   `--input-driver.so
|   `--xlibre-25.0/
|       |--drivers/
|       |   `--xlibre-driver.so
|       |--extensions/
|       |   `--xlibre-extension.so
|       `--input/
|           `--xlibre-input-driver.so
`--protocol.txt

So I presumed based on the commit that the drivers hosted here, should all go under ${PREFIX}/lib/xorg/modules/xlibre-ABI/, but the build files of the drivers I checked all have their default set to ${PREFIX}/lib/xorg/modules/.
For example:
X11Libre/xf86-input-keyboard
X11Libre/xf86-video-nv
X11Libre/xf86-input-mouse
and ...

So should they go to /lib/xorg/modules/xlibre-ABI/ or not?
If yes, I think there should be a change of the default directory in the build files across all of the drivers here.

Drivers should all go to the per-ABI directory, as specified xorg-server.pc file.

If some drivers aren't honoring that yet, then it's a bug. Feel free to file tickets in the corresponding repos or submit PRs.
